Wilson is veteran who spent the last season on the injured reserve and was considered very much a long shot to make this season's roster. The move coincides with the Patriots signing of safety Pat Chung, whose contract details were revealed today.
Wilson carried a $1.833 million cap hit and his release frees up $1.166 million in cap space- essentially all of Pat Chung's contract and even more.
The Patriots felt comfortable moving forward with its secondary and are under the belief that Devin McCourty, Duron Harmon, Pat Chung, Tavon Wilson, and Nate Ebner can provide enough value at safety beyond what Wilson could have provided. All five provide more special teams value, which is clearly a deciding factor.
Don't be surprised if the Patriots spend a late round draft pick on another strong safety in order to add to the camp competition and to push some of the veterans who haven't met expectations.
